Ordering Examples:
RS3-053.3S 4.5-9Vin 3.3Vout Single 2:1 Input Voltage 1kVDC Isolation
RS3-1212D/H2 9-18Vin ±12Vout Dual 2:1 Input Voltage 2kVDC Isolation
RS3-2415D/H3 9-27Vin ±15Vout Dual 3:1 Input Voltage 3kVDC Isolation
Notes:
Note2: add „Z“ for 3:1 Input Voltage (24= 9-27VDC or 48= 20-60VDC)
Note3: add suffix „/H2“ for 2kVDC isolation or „/H3“ for 3kVDC isolation, without suffix = standard 1kVDC isolation
